Question

A solid sphere rolls without slipping with velocity v and presses a spring of spring constant k as show in fig. Then the compression in the spring will be :

Answer 1

Answer:

A block of mass m=25kg on a smooth horizontal surface with a velocity →v=3ms-1 meets the spring of spring constant k=100N/m fixed at one end as shown in figure. The maximum compression of the spring and velocity of block as it returns to the original position respectively are.

Answer 2

Answer:

Explanation:

I of solid sphere is 2/5MR2

So rotational k.e/translational k.e

Is 2/5

So total energy is 7/5 × 1/2mv2

So 7/5 × 1/2mv2 = 1/2Kx2

So x = v✓7m/5k
